Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Idis also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can the use of specific data recovery software or services impact the success rate of data retrieval from NAS Idis DR-6332PS-SA devices?

The success rate of data retrieval from NAS Idis DR-6332PS-SA devices can be influenced by the use of specific data recovery software or services. However, it is important to note that the success rate ultimately depends on various factors such as the severity of the data loss, the condition of the NAS device, and the expertise of the data recovery professionals.

Using specialized data recovery software designed for NAS devices can increase the chances of successful data retrieval. These software tools are specifically developed to handle the complexities of NAS systems and can often recover data from various storage configurations.

Similarly, employing professional data recovery services with experience in handling NAS devices can significantly impact the success rate. Data recovery experts have the necessary tools, knowledge, and resources to deal with complex data loss scenarios and can often recover data that might be deemed unrecoverable by regular software.

It is important to note that in severe cases of data loss, such as physical damage to the NAS device or multiple drive failures, the success rate may be lower, regardless of the software or service used. In such situations, professional data recovery services with cleanroom facilities and specialized hardware may be required to maximize the chances of successful data retrieval.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS DR-6332PS-SA can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
